That's true. But you are looking in the budget section: it is ultralight, high R rating and budget category. You can't choose three things from price-quality-comfort trio.
I have one from flame's creed, 5.8R which is at 490g. There are several brands, but i think most pads that look similar and from a common (ali) brand sell the same pad, just under a different name. Had it for about 2 yrs now, and around 15-20 nights out. No failures so far, and didn't feel cold at lowest i encountered (3C). For me, it was a worth purchase and i'm satisfied with it.
I'm exactly the same height and almost the same weight as you and i'm also a side sleeper. I use Naturehike air mattresses. In Germany. I am happy with the price, quality and weight. The specifications according to Amazon: My 3.5R mummy one is 440g, my 5.8R rectangular one is 570g.
I'm 1.75cm x 70kg and I use the naturehike 5.8r, I find It quite comfortable and warm. You can find it around 90-100€, sometimes less depending on the offers
